Title:
【発明の名称】適応性調節用にpH滴定曲線を見積る方法
Document Type and Number:
Japanese Patent JP2632609
Kind Code:
B2
Abstract:
A method of estimating pH titration curves, for use in the adaptive control of pH in a process, comprises gathering data points which each represent the ratio between a reagent added to the process and a flowrate to the process at a measured pH, storing the data points in a bin system according to the measured pH, and using the stored data points to create a model of the titration curve for use in controlling the addition of reagent. Older points are replaced by newer points during the process continuously to update the model. The model is used to generate a gain schedule for operating a PI controller (16) which controls the addition of reagent to the process.
